+What Ben's working on now.
+--------------------------
+
+Workspace exhaustion heuristics.
+
+Does SET work correctly?
+
+Update q2c input format description.
+
+Rewrite output subsystem, break into multiple processes.
+
+CROSSTABS needs to be re-examined.
+
+RANK, which is needed for the Wilcoxon signed-rank statistic, Mann-Whitney U,
+Kruskal-Wallis on NPAR TESTS and for Spearman and the Johnkheere trend test (in
+other procedures).
 
 TODO
 ----
 
+Make valgrind --leak-check=yes --show-reachable=yes work.
+
+Add Boolean type.
+
+Add NOT_REACHED() macro.
+
+Add compression to casefiles.
+
+Expressions need to be able to abbreviate function names.  XDATE.QUARTER
+abbreviates to XDA.QUA, etc.
+
+The expression tests need tests for XDATE and a few others, see
+tests/xforms/expressions.sh comments for details.
+
+Expressions need random distribution functions.
+
+There needs to be another layer onto the lexer, which should probably be
+entirely rewritten anyway.  The lexer needs to read entire *commands* at a
+time, not just a *line* at a time.  It also needs to support arbitrary putback,
+probably by just backing up the "current position" in the command buffer.
